Cell structure 1
This organelle acts as the “control center” of the cell.
What is the nucleus?
This outer boundary controls what enters and exits the cell.
What is the cell membrane?
This jelly-like material fills the cell and holds the organelles in place.
What is cytoplasm?
The cell membrane is described as “_____________________,” meaning it allows these to pass.
What is semi-permeable?
DNA is stored in this cell structure.
What is the nucleus?
This organelle stores water, nutrients, and waste for the cell.
What is the vacuole?
The nucleus is surrounded by this double-layered structure that protects its contents.
The nucleus is surrounded by this double-layered structure that protects its contents.
This model describes the membrane as a flexible layer made of proteins floating in a sea of lipids.
What is the fluid mosaic model?
_________ cells often have one large of vacuole
What are plant cells?
This dark, dense region inside the nucleus is responsible for making ribosomes.
What is the nucleolus?
The cell membrane is primarily composed of these molecules arranged in a bilayer.
What are phospholipids?
____________ cells have several small ones.
What are animal cells?
This type of cell lacks a nucleus entirely.
What is a prokaryotic cell?
This process allows molecules to move from high to low concentration without energy through the membrane.
What is diffusion?
The cytoplasm cushions these tiny “machines” that carry out cell functions.
What are organelles?
